[counterintuitive] Using 'Let's think step by step' as a magic bullet for complex reasoning

Replace generic Chain of Thought triggers with domain-specific structural instructions \(e.g., '1. Identify constraints. 2. Write pseudocode. 3. Implement.'\) or use native reasoning models \(o1/o3\) that handle CoT internally.

Journey Context:
The zero-shot CoT phrase from 2022 forces modern models into verbose, unfocused rambling. It is a blunt instrument that often leads to hallucination during long, unstructured reasoning traces. Modern instruction-tuned models respond better to explicit cognitive architectures that constrain their reasoning steps, while frontier reasoning models handle CoT natively and perform worse if forced to show step-by-step text.
